: Figure 14 is a longitudiual section illustrating (@l. is-so) Figures 1 to e inclusive, coiiipiises e iuseluge 1 79 constructed oieierooiy oi tl'iiu wooden stiles to form o hollow, elongated body, the iorwoi'd portion 2 of which is of uniform, trons-verse dimensious, while the rest portion at is oi si'cduuilv conversing form towerd the tail end oi the eiercpierie to thereby simulate the us clone fuselage structure. hollow if traced by hollow, rectangular iiumes i, one such frame being particularly arranged ot the iorword open end oi the portion 2. The opposite 80 end of the toil or converging portion is provided with em inteeior solid block ii so tlie iuseioge structure is of comparatively rigid, though light, formation.

The wine structure, the sliowinsloeine; oi the ruouoplene type, is securecl to the upper surioce oi the forward portion 2 of the fuselage. This wine structure comprises a single frame, the item gitudineli sitie tiers ii of which are preierolcly wooden strips held in desired spaced reiotioii by transverse woodenloroces l. The ends oi the wings, in order to ovoid breakage in the event the aeroplane iolls to the ground or contacts with other obstructions, are preferably formed of appropriate wire lengths e bent into rounded form to complete the sleeps. of the wing, with their terminals secured to the ends of the wooden strips 6, as more particularly shown in Figure i.

As stated, the wing is secured transverse the body portion 2 of the fuselage and to the upper surface of the latter to permit the convenient removal of this wing portion, if necessary, for repair or replacement. The attachment is made through the medium of clips, illustrated more particularly in Figure 6, and including relative- 1 1y broad base portions 9 which bear directly upon the upper surface of the portion 2 of the fuselage and narrow sections 10 which overlie the front and rear edges of the wings. A fastening means, such as a pin 11, may be passed through approiii) priate openings in the portions 9 and to of the clip, securing the wing removably to the fuselage. The clip is preferably constructed of a single piece of metal appropriately formed and the broad portions 9 may, if desired, be more or less fixedly secured to the fuselage, permitting the obvious and convenient application or removal of the wing in a simple, desired manner.

The wing frame including the parts 6, 7 and 8 is to he covered by a cloth covering 12, preferably of such weave as to permit a limited passage of air through the material when the aeroplane is being flown. This avoids undue gyrations of the aeroplane in use, assists it to remain steady in flight, and yet provides sumcient support from the body of air to permit the plane to fly naturally and easily. The tail frame is secured to the upper surface of the converging portion 3 of the fuselage, this frame including a wire section 13 bent into appropriate form" and covered with material 14 similar to the material used for the wing. The tail is secured to the converging portion 3 of the fuselage loy clips 15 and 16 similar in form to the clip shown in Figure 6, though possibly of less transverse area, .the underlying broad portion lying on the fuselage surface and the overlying lip bearing upon the upper surface of the wing, with both clips secured to the fuselage by removable pins, tacks or nails, indicated at 17.

The landing gear is shown in the form of an inverted U-shaped frame 18, the cross bar 19 of which is secured to the lower surface of the pertion 2 of the fuselage, with the lower terminals .of the side bars of the frame carrying wheels 2d simulating the landing gear. The frame is preferably of a width exceeding the corresponding dirnension of the fuselage to space the wheels apart in more exact simulation of the landing gear of an aeroplane, as indicated in Figure l.

as an essential part of this preferred form, as well as the modified forms, auxiliary supporting means are to be used, if desired. For this purpose, an inflatable has, preferably of rubber or the like and-indicated at 21, is inserted in the fuselage, the bag being of appropriate form for this insertion and having a valved end 22 designed to be arranged adjacent the open end of the body portion 2 of the fuselage to permit the hag to he filled with a buoyant gas. of course,

the area of the parts and the particular gas used is such as to render the aeroplane structure as a whole inherently buoyant, in that if released it will rise. in the air similar in this respect to the conventional toy balloon, The tail skid of the hotly is represented by a screw eye 23 threaded through the lower surface of the rear end of the portion 3 of the fuselage and into the block 5, the eye portion losing rearwardly deflected to simua tail skid, as shown more particularly in Figure 2.

a metallic cap 24 is designed to fit frictionally over the open end of the body portion 2 of the fuselage, the'forward portion of the cap heme convergent and terminating in i the form of a spindle 25 on which is mounted for free rotation an element 26 in the form of an aeroplane propeller. through the air and the use of such as a lrite, it is apparent that the propeller will be rapidly revolved due to passing air currents, and thus further simulate the appearance of an aeroplane during the flying of the toy.

If preferred, and as contemplated, the fuselage 1 may be constructed of light metal pressed into proper form, as indicated at 27 in Figures 7 and in the movement of the aeroplane ro ues?" 8. In other respects the structure is as described in connection with the preferred form.

In Figures 9 to 18 inclusive there is shown a slightly modified form of construction having to do more particularly with simplified detail designed with a view to rendering the construction of economical formation and assemblage. In this form, the fuselage, indicated at 28, is of converging outline from the front to the rearand is formed of spaced bars 29 terminally anchored in blocks 30 and 31 dimensioned according to the forward and rear ends of the fuselage respective-- ly, the bars 29 converging according to the desired outline plan of the fuselage. These bars, as well as the end bloclrs, are covered by a fabric covering 32, preferably of material corresponding to that shown for the wings and tail in the preferred form, in order to complete the outline formation of the fuselage. V

The wing of this form, indicated more particularly in Figures Q and lo, constitutes a full wire complement including front and rear wire bars 33, appropriately formed end wire bars 34, crossed wire struts 35, and a longitudinal brace strip 36. in this form, the central portion of the that is, the portion in contact with the upper surface of the fuselage, is parallel to such fuselage surface, as indicated at 37, and from this central portion 37 the extended portions of the wings 38 incline upwardly and outwardly, as more particularly shown in Figure 10. lhis is with a view to simulating the accepted type of aeroplane and lending more reality to the toy.- The wing is secured to the longitudinal bars 28 by clips corresponding to the clips shown in Figure 6 and indicated at 39, the broad portions of the clips being of sumclent length to overlie the upper bars 28.

The tail plane for this type of aeroplane is shown more particularly in Figure 13, wherein a single wire length is bent into appropriate form, as at so, the terminals of the wire being projected in parallel contact with the longitudinal median plane of the frame, as at l1. covered with material similar to that previously described, and the tail frame is secured to the rear end of the fuselage hy clips, one of which is shown particularly in Figure 1'7. This form of clip comprises a i-=forrn section having a cross head 42 and a stem 43. In applying this clip, the stem is passed around the inner end cross bar 43' of the tail frame and the head portion is looped around the bars ii of the frame, the clip being then secured inappropriate manner to the longitudinal bar of the fuselage or to the rear block 31 thereof, and the bars at remote from the cross bar at are united by a loop strip of metal as, and the tail skid, here shown as an eye-bolt &5, is passed through the block 31 at the rear end of the fuselage and through the clip it, being removaloly headed or provided with suitable fastening means above the frame. The eye-=holt below the frame is bent rearwardly to provide the to and the frame is thus held in position, though The cross her is of the landing frame is riveted or otherwise secured to the clips capable of convenient removal when desired for repair or replacement.

The frame bars 29 are projected in advance of the forward block 30 of the fuselage and thus provide a rectangular outline to receive scan 50 hav ing a spindle 51 on which in this instance is secured a propeller 52. The spindle is extended rearwardly through the frame bar and arranged in hook form, as at 53. A similar hook bar 54 is secured in a transverse strut 55 of the fuselage. A rubber band or like torsional element 56 is connected with the respective books so that the bar may be put under tension by turning the'propellor by hand, serving to operate the propeller on the release of such turning strain,

The cap 24 of the preferred form, and also the cap 5d of the modified form, is provided with an eye 5'? to which one terminal of a cord 58 is connected, the other terminal being connected to the tail skid 23 oi the preferred form and so in the modified icrrn. ihe usual cord 59 is connected at an appropriate point to the cord 58% to be used in flying the aeroplane,

As constructed, it will be apparenttliat the aeroplane parts are rigidly assembled and associ-- ated in a manner which renders the toy littleliable to breakage. The parts are, however, readily separable when necessary for repair or replacement, thus providing the ideal toy, in that broken parts may be readily andconvenientlyreplaced by anyone even with little skill. The toy is flown as a kite in the usual manner, or where the buoyant body is employed, as is contemplated, the flying movement is more or less of a restraining movement in guiding the toy, which floats in the air under its own buoyancy.
